Vizio TV Won’t Turn On—What to Do?

If your Vizio TV suddenly doesn’t turn on, it can be very frustrating. Buying a new TV can be expensive, and getting it repaired can be costly and time-consuming.

Vizio TV Won’t Turn On—What to Do?

Don’t worry, though. If your Vizio fails to power on, there’s no reason to panic. There are a couple of possible reasons why the scenario occurs, and in most cases, it’s not due to a broken TV. Usually, it just takes a few minutes and some troubleshooting to get your TV back up and running.

What to Do if Your Vizio TV Won’t Turn On

Before we jump into troubleshooting your TV’s problem, we need to determine if it’s getting power or not.

  • It’s simple, check the standby light on your TV to see if it’s on or not. If you see the red indicator light, then that means your TV is in Standby mode. If you see then the blue indicator light and there’s still a black screen, then that means your TV is on but might be on a different input screen or could have an issue with the backlight. If you don’t see a light at all, then that means your TV isn’t receiving power for some reason.

Troubleshooting a Vizio TV that has the Standby Light On

Here are some potential reasons why your Vizio TV won’t turn on even though the standby light is on.

Check the Remote

If you can’t turn on your Vizio TV using a remote, there might not be anything wrong with the TV at all. Instead, the issue might be with the remote.

  • One of the most common issues is that the batteries are dying or they’re already dead. To see if this is the case, try replacing the batteries and turning the TV on again.
  • If there’s still nothing happening, remove the batteries from the remote and press and hold the Power button on your remote for 15 seconds. After pressing the Power button for 15 seconds, reinsert the batteries and try turning the TV on.

If your TV’s standby light isn’t on, the red light in the corner that’s on even when the TV isn’t, then you most likely have an issue with a lack of power.

Check the Vizio TV’s Power Source

To start, checking the power is the next logical step.

  • The first thing you’ll want to do is see if pressing the Menu button yields any results. Sometimes, the TV is on but displays a blank screen. Both the remote and the TV include a Menu button. Try pressing both buttons (not simultaneously) to see if the menu pops up.
  • If the menu test fails, the TV may indeed be off, and the power source might be an issue. Ensure that your TV is fully plugged into a power outlet before trying to turn it on again.

Check the Condition of the Power Cord

The thing that can often prevent your TV from turning on is a loose or damaged cord. A loose power cord sometimes causes problems for even the most technically savvy among us.

Power Cord Inspection

  • To ensure that the cord fits well, check its connection to both the power outlet and the TV, making sure both connections are plugged in. Even a slightly loose power cord connection can interrupt the flow of electricity to your TV, and it’s not always apparent that your TV is unplugged from its power source. See if the cord is correctly plugged into the outlet. A good idea would be to unplug it and then plug it back in to ensure it is secure. Another thing you can try is to plug the cord into another outlet.
  • After you’ve checked the power outlet in the wall, ensure the cord securely connects to the back of the TV. A loose power wire connection happens more often than you might think, especially if you have children or pets that run around the TV or you have a long run to the power strip. Longer runs mean tighter cords that can loosen when rotating the TV or when moving it around. You can always unplug the power cord from the TV and plug it back in to ensure it is fully inserted and secure.

If checking the remote for functionality, testing the TV’s power source (outlet), and inspecting the TV’s power cord doesn’t solve the problem, there are a few more things you can try to resolve the issue.

Power Cycle Your Vizio TV
